2511 first loc_chain location if NULL before. Always use just
2512 cur_loc instead of first loc_chain location. When cur_loc_changed
2513 is false, when not --enable-checking=rtl just don't emit any note.
2514 When rtl checking, compute the note and assert it is the same
2515 as previous note. Clear cur_loc_changed and in_changed_variables
2516 at the end before removing from changed_variables.
